The Universe is a big place.
I mean, really big. Big everything for anything. Literally, big enough for everything. Everything you see, everywhere you go, it’s all inside. And there’s room for all of it, with space to spare. I get used to it sometimes, and then, suddenly, I’m thrown into a state where I’m forced to remember just how much of the Universe there is.
